Top GOP senators call for reform, 'consequences' in wake of law enforcement 'leadership failure'

Top GOP senators criticized recent law enforcement failures by the FBI and other groups Sunday, calling on President-elect Trump's administration to enact reforms.

"The FBI is an agency that I think is in need of reform, and it needs a good makeover, so to speak, and probably a good amount of housecleaning when it comes to the perception the American people have of it and these institutions that the American people need to have confidence and trust in," Thune said Sunday.

He added that Trump's nominee to lead the FBI, Kash Patel, "understands the mission."

"There has to be leadership at the top. And if the leadership failed, as you describe it, then absolutely there has to be consequences. Period. End of story," Cassidy said.

"Now, I think we're going to have a kind of complete review of everything from top to bottom. And if that's the way it ends up shaking out completely, she should be replaced," he added, referencing New Orleans Police Superintendent Anne Kirkpatrick.

"The FBI has a no-fail mission. There is no room for error. When they fail, Americans die. It's a necessity that Kash Patel gets confirmed ASAP," a source close to Trump told Fox News Digital on Thursday morning. 

Patel is one of many incoming Cabinet nominees who will need to go through Senate confirmation after Trump is inaugurated later this month.
